按对象属性循环遍历对象数组

Question

我有一系列对象，其中包含一些有关我要触发的流行音乐的信息。 它看起来像这样：

[  
   {  
      "url":"www.fakeurl/redirect1",
      "providerName":"ebay",
      "retailerName":"eBay",
      "providerAndRetailer":"ebayeBay",
      "popAllowed":true
   },

   {  
      "url":"www.fakeurl/redirect2",
      "providerName":"pricerunner",
      "retailerName":"Currys",
      "providerAndRetailer":"pricerunnerCurrys",
      "popAllowed":true
   },
   {  
      "url":"www.fakeurl/redirect3",
      "providerName":"kelkoo",
      "retailerName":"Currys",
      "providerAndRetailer":"kelkooCurrys",
      "popAllowed":true
   },
   {  
      "url":"www.fakeurl/redirect4",
      "providerName":"ebay",
      "retailerName":"eBay",
      "providerAndRetailer":"ebayeBay",
      "popAllowed":true
   },
   {  
      "url":"www.fakeurl/redirect5",
      "providerName":"pricerunner",
      "retailerName":"Argos",
      "providerAndRetailer":"pricerunnerArgos",
      "popAllowed":true
   },
   {  
      "url":"www.fakeurl/redirect6",
      "providerName":"ebay",
      "retailerName":"eBay",
      "providerAndRetailer":"ebayeBay",
      "popAllowed":true
   },
   {  
      "url":"www.fakeurl/redirect7",
      "providerName":"ecn",
      "retailerName":"Argos",
      "providerAndRetailer":"ecnArgos",
      "popAllowed":true
   }
]

我还提供了一系列要触发命令的提供程序：

let acceptedProviders = ['ebay', 'connexity', 'ecn', 'kelkoo', 'nexttag', 'pricerunner', 'shopping'];

我想按我的acceptedProviders的顺序遍历数组。 当在对象中找到与“ providerName”属性匹配的内容时，我希望循环停止并添加“ popAllowed”属性：false，因此可以将其从列表中过滤掉。 然后它将再次循环，仍在我接受的提供程序数组中寻找名字，如果找不到，它将移至下一个，直到列表用尽。 我已经尝试过for循环，但是我似乎无法获得所需的结果。 任何帮助，不胜感激。

只需遍历数据并在每个迭代集中进行popAllowed（通过在可接受的提供程序数组中查找该提供程序）

 let acceptedProviders = ['ebay', 'connexity', 'ecn', 'kelkoo', 'nexttag', 'pricerunner', 'shopping']; let data = get_data(); data.forEach((item)=>{ item.popAllowed = acceptedProviders.indexOf(item.providerName) === -1; }); console.log(data); function get_data() { return [{ "url": "www.fakeurl/redirect1", "providerName": "ebay", "retailerName": "eBay", "providerAndRetailer": "ebayeBay", "popAllowed": true }, { "url": "www.fakeurl/redirect2", "providerName": "pricerunner", "retailerName": "Currys", "providerAndRetailer": "pricerunnerCurrys", "popAllowed": true }, { "url": "www.fakeurl/redirect3", "providerName": "kelkoo", "retailerName": "Currys", "providerAndRetailer": "kelkooCurrys", "popAllowed": true }, { "url": "www.fakeurl/redirect4", "providerName": "ebay", "retailerName": "eBay", "providerAndRetailer": "ebayeBay", "popAllowed": true }, { "url": "www.fakeurl/redirect5", "providerName": "pricerunner", "retailerName": "Argos", "providerAndRetailer": "pricerunnerArgos", "popAllowed": true }, { "url": "www.fakeurl/redirect6", "providerName": "ebay", "retailerName": "eBay", "providerAndRetailer": "ebayeBay", "popAllowed": true }, { "url": "www.fakeurl/redirect7", "providerName": "ecn", "retailerName": "Argos", "providerAndRetailer": "ecnArgos", "popAllowed": true } ]; } //console.log(data)
